Two college seniors had a week of exams coming up. They decided   to  party  instead.

　　Their  biggest  exam   was   on   Wednesday   and   they  showed  up  telling  the  professor  that  their  car  had  broken  down   the  night  before  due  to a very  flat  tire  and they needed a  bit  more time to study. The professor told them that they could have another day to study.

　　That evening, both of the boys  crammed  all  night  until they were sure that they knew just about everything. Arriving to class the next morning, each boy was told to go to separate classrooms to take the exam.

　　Each shrugged and went to two different parts of the building. As each sat down, they read the first question. "For 5 points, explain the contents of an atom."

　　At this point, they both thought that this was going to be a piece of cake, and answered the question with ease. Then, the test continued.

　"For 95 points, tell me which tire it was."
